CROSS REFERENCE TO RELATED APPLICATIONS

This application is a continuation of PCT International Application No. PCT/EP2016/065720, filed Jul. 4, 2016, which claims priority under 35 U.S.C. § 119 from German Patent Application No. 10 2015 212 972.1, filed Jul. 10, 2015, the entire disclosures of which are herein expressly incorporated by reference.

BACKGROUND AND SUMMARY OF THE INVENTION

The invention relates to a motor vehicle having a folding top or a roof cover which is movable from a closed position in which a vehicle interior is covered into a stowage position in which the vehicle interior is open to the top.

DE 199 08 499 C1 discloses a wind partition arrangement for open motor vehicles. The wind partition is oriented substantially vertically and covers the head restraint region behind the backrests of the vehicle seats arranged next to one another. Furthermore, the wind partition has a horizontally arranged covering part which covers a clearance between the wind partition and a rear wall of a passenger cell. Air outlet nozzles via which the head restraints can be impinged with warm air are provided in the covering part.

It is an object of the invention to provide a motor vehicle in which cold air is prevented from flowing forward from the rear region to the front seats when traveling with an open folding top.

This and other objects are achieved by a motor vehicle according to the invention having a folding top or a roof cover which is movable from a closed position in which a vehicle interior is covered into a stowage position in which the vehicle interior is open to the top.

The motor vehicle has a body with opposite side walls in each of which a door cutout opening is formed. A side door is pivotably arranged in the respective door cutout opening. The respective side wall has a (B) body pillar adjoining the side door.

Two front seats are arranged in the vehicle interior, wherein a front seat has a seat cushion, a backrest and possibly a head restraint. The two front seats are spaced apart from one another by a center console, wherein a rear region adjoins behind the front seats.

At least one air outlet opening or air outlet nozzle is advantageously formed at a rear end of the center console, through which air outlet opening or air outlet nozzle warm air can flow out upward and/or forward between the two backrests of the two front seats. In addition, air outlet openings are provided in the two opposite (B) body pillars, through which air outlet openings warm air can flow out forward in the direction of the backrests of the front seats.

In an advantageous embodiment, adjustable nozzles or the like are arranged in the present air outlet openings of the center console and the present air outlet openings in the two opposite (B) body pillars.

The air outlet nozzles situated in the air outlet openings are advantageously motor-adjustable in their position.

In an advantageous embodiment, the air outlet openings are connected to the present heating device and/or air-conditioning device and the control device and/or regulating device connected thereto.

Other objects, advantages and novel features of the present invention will become apparent from the following detailed description of one or more preferred embodiments when considered in conjunction with the accompanying drawings.

BRIEF DESCRIPTION OF THE DRAWINGS

FIG. 1 is a side view of a partially sectioned motor vehicle with an open folding top.

FIG. 2 is a view from above of the motor vehicle shown in FIG. 1.

DETAILED DESCRIPTION OF THE DRAWINGS

FIG. 1 shows a motor vehicle 1 in which a folding top 2 is situated in a stowage position 3 in a folding-top compartment or in a luggage compartment 4. Two front seats 9 a, 9 b are arranged in front of the rear region 6 in the vehicle interior. The two front seats 9 a, 9 b are spaced apart from one another by a center console 11. Each front seat 9 a, 9 b has a seat cushion 32, a backrest 21 a, 21 b and possibly a head restraint 33.

When the motor vehicle 1 travels with an open folding top in the direction of travel x in accordance with FIG. 1, an air space 5 in a rear region or in a region 6 between the two front seats 9 a, 9 b and the luggage compartment 4, or possibly present rear seats 7, cools down by virtue of an overpressure from above.

The air flow 8 created as the motor vehicle 1 travels is illustrated in FIG. 1 by a linear flow progression. The air flow 8 presses past the two front seats 9 a, 9 b from the rear region 6 in the direction of travel x. A respective person seated on one of the two front seats 9 a, 9 b is cooled by the air flow 8.

In the embodiment shown in FIG. 1, a pivotable air outlet nozzle 12 or a forwardly and/or upwardly directed warm air outlet of a fan is provided at a rear end 10 of a center console 11. The outflowing warm air 13 is symbolically illustrated by an arrow 14.

As shown in FIG. 2, side walls 34 a, 34 b are formed on both sides of the body 1 a of the motor vehicle 1. In the opposite side walls 34 a, 34 b there is formed a respective door cutout opening 16 a and 16 b. A side door 15 a and 15 b is in each case pivotably arranged in the respective door cutout opening 16 a, 16 b. The respective side wall 34 a, 34 b has a (B) body pillar 17 a, 17 b adjoining the respective side door 15 a and 15 b.

As shown in FIGS. 1 and 2, air outlet openings 18 and 19 are formed in the respective B body pillar 17 a, 17 b. In one embodiment, the air outlet openings 18, 19 can be formed such that warm air 13 a, 13 b flows forward in the direction of a respective backrest 21 a, 21 b of the respective front seat 9 a, 9 b corresponding to an arrow 18 and 19.

In another embodiment, air outlet openings 22 a and 22 b are provided via which warm air 13 a, 13 b flows in the vehicle transverse direction corresponding to an arrow 24 a, 24 b.

In a further embodiment, both air outlet openings 18, 19 and air outlet openings 22 a, 22 b can be provided, from which air flows forward corresponding to the arrows 18 and 19 and flows in the vehicle transverse direction corresponding to arrows 24 a, 24 b. The air outlet openings 12, 18, 19, 22 a, 22 b can be provided with a ventilation louver.

The emerging warm air 13 at the air outlet nozzles 12 a and 12 b on the center console 11 and the emerging warm air 13 at the air outlet openings 18, 19 on the B body pillars 17 a, 17 b results in a “warm air curtain” which prevents cold ambient air of the head wind flowing forward from the rear region 6 past the backrests 21 a, 21 b of the front seats 9 a, 9 b or results in such forward-flowing cold air being heated.

In addition, the effect of preventing the cold ambient air of the head wind flowing forward from the rear region 6 past the backrests 21 a, 21 b of the front seats 9 a, 9 b can be boosted as a result of the fact that the air outlet openings 26 a and 26 b present in an instrument panel 25 at the opposite ends 27 a, 27 b of the instrument panel and the air outlet openings 29 a, 29 b situated in the center 28 at the level of the center console 11 discharge warm air 13 a, 13 b in the direction of the respective front seat 9 a, 9 b. The warm air 13 a, 13 b flowing out through the air outlet openings 26 a, 26 b and through the air outlet openings 29 a, 29 b is denoted by arrows 30 a, 30 b and 31 a, 31 b.

The present air outlet openings 12 in the center console 11 and the present air outlet openings 18, 19; 20 a, 20 b; 22 a, 22 b in the two opposite (B) body pillars 17 a, 17 b are connected to the present heating device (not shown) and/or air-conditioning device (not shown) and the control device (not shown) and/or regulating device (not shown) connected thereto.

The foregoing disclosure has been set forth merely to illustrate the invention and is not intended to be limiting. Since modifications of the disclosed embodiments incorporating the spirit and substance of the invention may occur to persons skilled in the art, the invention should be construed to include everything within the scope of the appended claims and equivalents thereof.
